UNIVERSAL JOINT.

Specification of Letters Patent. Patented Sept. 14, 1909.

Application filed August 14, 1908. Serial No. 448,477.

To all who-m it may concern:

Be it known that I, DANIEL CoRooRAN, a

citizen ofthe United States, anda resident of Yonkers, in the county of Westchester and State of New York, have invented a new and Improved Universal Joint, of which the following is a full, clear and exact description.

My invention relates to universal joints and has for its object to provide one consisting of a disk having a semicurcular flange on each of its sides, the planes of the flanges being substantially at rightangles to the disk and tol each other, and two shafts in one of the terminals of each of which there is a semicircular slot, each of thel flanges being disposed in one of the slots, there being curved'slots in each of the flanges and a pin disposed in each of the shafts through the slots respectively.-

Other objects of 'the invention will appear in the following complete description.

In this specification I will describe the preferred form of my invention but it will do not limit myself thereto, as I consider myself entitled to all forms and embodiments of the invention which may be held. to fall within the scope of the appended claims.

Reference is to be had to the accompanying drawings, fication, in which similar characters of reference indicate corresponding parts in all the figures, in which- Figure l is a 'plan view showing my universal joint in use connecting two shafts; Fig. 2 is an enlarged sectional view of my universal joint showing the curved slots in fthe flanges and the pins disposed therethrough; Fig', 3 is a similar sectional view but w1thout the curved slots andpms; and secure 1n the slotsy at the terminals of the shafts with which the semicircular flanges, may engage.

By referringto the drawings, it will be seen that shafts 1' are coupled together by my universal joint 2, the shafts 'being journaled in bearings 3. The universal joint-2 Jconsists of a central member or disk l, to each side of which 1s secured a semicircular flange 5, the planesof the flanges being `substantially at right-angles to the central member or disk 4 and to each other. In the construction of my universal` joint, I find it advantageous to make the central member or disk 4 with integral flanges 5, but it will forming a part of this specie of course, be understood that this is merely a detail of construction, and that if desired, the flanges 5 may be constructed separately and be'attaelied to the central member or disk 4 in any approved manner. Each of the shafts 1 has .a slot 6 in its terminal, and in these slots 6 are disposed wear members 7, the wear members having annular surfaces 8 and dowels 9, the dowels 9 being disposed in recesses in the shafts and the concave surfaces 8 extending between the sides 10 of the slots 6. The shafts are then ready to be united by means of the universal joint 2 and when the flanges 5 are disposed in the slots 6 with their peripheries in close proximity to the concave surfaces 8, of the wear members 7, and the shafts are journaled in bearings, it will be found that the shafts are coupled together by means of the universal joint 2 and that they will rotate in unison. Vhen desired annular slots 1l may be made in each of the flanges 5 and pins 12 may be driven through the sides of the slots 6 land through the annular slots 11 in the flanges 5 and by thisv means the universal joint will -be more securely connected between the shafts l. When the shafts l are connected in the manner which has been described, by my universal joint, it will be found that y a very simple construction, great strength is obtained and that the device takes up comparatively little space. Having thus described my invention, I claim as new and desire to secure by Letters Patent:

l. In a universal joint, two members, there 4being a concave slot in one of the terminals of each of the members, and a central disk having a flange on each of its two sides, the flanges having their peripheries convex, with their centers substantially `at the center .of the disk, the flanges being continued until they unite with the central disk near its periphery, the flanges fitting snugly the concave slots respectively, in which they are disposed, the planes of the flanges being disosed at an angle to each other and to the central disk.

2.' In a universal joint, two members, there being a concave slot in one ofthe terminals of each of the members, a central disk having a flange on each of its two sides, the

flanges having their peripheries convex, with they unite with the central d isk near its.4

periphery, the flanges fitting snugly the con- /CJI cave slots respectively, in which .they are disposed, t'liep'lanes of the 'flanges being disvposed at an anglev to eachother and' to the memiers, '.a. central member having flanges on each of itstwosi'des, the planes ofthe flanges being at an angle to each other, the

. Alaiigge's being disposed in the slots respecs tively, there being'iannular slots in each of thelaii'ges, andjpins in the members which are disposed .inthe annular slots respectively.

214. In the universal joint, two'members, a concave slot in one of the terminals of each 'l .of themembe'rs, acentral member having flanges on each 'ofi/cs two sides, the peripheries of-theflanges being convex, the planes of the flanges being substantially at right .angles to the body of the central member and to each. other, the flanges being disposed iii the concave slots, there being, annular, 4slots in each of the flanges, and pins in thel members which are disposed' in the 'annular slots. respectively. 15, In 'al universal Joint,

bei-having a flange on veach of its two sides, the peripher'ies of theflanges being convex,

` the planes of theflangesbeing substantially' at right-angles to the body of the central member and to each other, the flanges being disposed in the concave slots, there being antwo. members, a concave slot 1n one of the terminals of each` oft-he members respectively, a central memnular slots in each'of theflanges, pins in the l memberswliicli are disposedv in the annular slots respectively, and bearings in which tlie members l"are journaled respectively; Y
